OPGW (Optical Ground Wire) is a specialized cable used in electrical power transmission lines that combines the functionality of a ground wire with optical fiber capabilities. It serves a dual purpose: protecting transmission lines from lightning strikes while providing a medium for high-speed data communication. This hybrid construction makes OPGW an essential component in modern power grid infrastructure. opgw It ensures reliable communication for monitoring and controlling electrical networks, enabling utilities to manage system performance effectively. By integrating optical fibers into the ground wire, OPGW improves both safety and the operational efficiency of power transmission networks.
